Purpose: The purpose of this paper is to explore how vulnerable refugee children's education can be supported in the first asylum country during a long-term, complex crisis. More specifically, the authors examine the impact of a remedial education (RE) program on academically challenged Syrian refugees' sustained learning and well-being in Jordan during a protracted emergency. Design/methodology/approach: Using the 2012 United Nations human security framework, the authors analyze the quantitative results of program evaluation, supplemented by qualitative surveys and stakeholder interviews that asked about the aspirations of refugee children and their guardians, their school experience and the refugee-host community relationship. Findings: The authors' data suggest that the program enhanced targeted Syrians' protection and empowerment. Their increased sense of safety and improved academic performance and learning motivation were likely owing to child-friendly classroom management and pedagogies that facilitated interactive and differentiated learning. Their human security was further strengthened when they learned with Jordanian children who experienced similar academic challenges and with teachers sympathetic to their plight. Meanwhile, a human security framework calls for humanitarian agencies' strategic engagement with local partners to ensure refugees' learning continuity. Originality/value: Refugee education studies in first asylum countries are rare. Even rarer are studies focusing on academically low-achieving refugees with full consideration of the protracted and complex nature of a crisis. This study suggests effective measures to increase their human security while calling for humanitarian aid organizations to use long-term thinking.
